摘要： The technical solution relates to the field of processing polymers and can be used in various branches of the national economy for manufacturing hollow articles of the bodies-of-revolution type (tubes), and in particular for manufacturing semifinished biodegradable polymeric stents which are usable in medicine for replacing hollow organs, for example blood vessels. The apparatus for manufacturing thin-walled bodies of revolution comprises a heatable expander which is mounted rotatably about a longitudinal axis, and a feeder for supplying moldable material, said feeder being mounted above the expander so as to be movable therealong, wherein the lower part of the feeder is heatable, the expander is hollow with a reflective internal surface, and the heater of the expander is in the form of a laser, the radiation of which is transported into the expander. The use of the apparatus will make it possible to reduce the thermal action on a polymer when producing semi-finished articles with defined geometrical dimensions from polymeric materials.
